No More Silos

Publicis Groupe has spent the past year reorganizing its agencies. Now, it’s looking to break down silos by operating all of its creative agencies on a single P&L by country, rather than by brand. So far, the shift will only take place within Publicis Communications, the group’s creative network; other Publicis networks, including media, will remain on P&Ls by brand.

Boo, Yahoo

Yahoo came clean about a massive data breach on Thursday, revealing hackers stole the account information of 500 million users in 2014. The names, email addresses, telephone numbers, birth dates, passwords and security questions were compromised by what the company is calling a “state-sponsored act.” “The stolen Yahoo data is critical because it not only leads to a single system but to users’ connections to their banks, social media profiles, other financial services and users’ friends and family,” Alex Holden, the founder of Hold Security, which has been tracking the breach, told The New York Times. “This is one of the biggest breaches of people’s privacy and very far reaching.” Wonder how Verizon feels about that.

Native ads receive 56% higher click-to-install rates than traditional banners, its only form of app-install advertising until now, Twitter said. The native product doesn’t include mobile app engagement ads, which prompt people to use apps they’ve already installed. More.
